Are many the types of wood and their provenances that we use in the making of our Supreme Casks. Below you will find the many kinds of wood that we select and carefully treat outdoors, in the open air, during a period of time that varies between 12 and 18 months. This is a treatment done in our facilities, that can be found 5Km's from the Atlantic ocean, giving it a preponderant and exceptional geographical location for the process of the wood maturation.

QUERCUS ALBA (American Oak)

Existing mainly in the west side of the United States of America, this species of wood can be found in the states of Missouri, Ohio, Illinois, Oregón and Tenesse. It's a wood that stands out mainly for it's hight density and low porosity, offering a highly aromatic feature during the period of maturation.

QUERCUS ROBUR (European Oak)

This species of wood grows mainly in the Limousine region, in the south-west of Aquaitaine, where it's estimated to exist around 7 million cubic meters of forest filled with this species of wood. However it can be found all around several large woods all around Europe, with a high incidence in Hungary, Romania, Ukraine, Russia and also in Spain, especially in Galicia.

QUERCUS PYRENAICA (Portuguese Oak)

Easy adaptability to the continental conditions of high and cold lands, existing in Portugal, specially in Trás-os-Montes and Beira Alta. It's a species that is considered as mid-light and sturdy temper. Does not support soaked or heavy soils, prefering areal textures. The wood possesses similar characteristics to other oaks, however, it's more unstable and is very prone to deformation and cracking during the drying process, which in turn, is very slow. It does however surprise with it's aromatic capability, that it confers during the maturation.

CASTANEA SATIVA (Portuguese Chestnut)

It is a large tree, very abundant in the interior, north and centre of Portugal. It's root system is powerful and robust, very expansive but shallow. It's growth is rapid, and it's tannin richness is around 8 to 10%. It's a species of great longevity, being able to reach ages greater than the millennium.
Very similar in appearance to the oak, with a noteworthy density, it is a kind of wood with little hardness and quite porous, requiring a very strict selection criteria.
